I search about a good tool that help me to Vectorize my pixel photos to enhance the quality but be a free tool ?

I work as a graphic designer sometimes i see some photos with bad quality like a blurred pixels . so I search about a good tool that help me to Vectorize my pixel photos to enhance the quality but be a free tool ? 

  • I use Inkscape to create svg (scalable vector graphics) files.  I've also used it to convert png and jpeg files into svg files.

    I call the one to the right, "Tux Bytes Apple"¹ →

    The reply-editor doesn't permit embedding (or uploading) svg files.  I embedded a png-version, instead.

    Inkscape is open-source.  And it's free. :-D

    ¹ An amalgam of 2 assets, neither of which I created.  I only converted, combined, and edited — changing colors, while adding gradients and transparency.

  • I should have mentioned... "Tux Bytes Apple" looks best on a black background.  Try it yourself — right-click→"Save image as...".  I don't have time to edit. :-P lol

  • I've usually just use the sharpen filter in GIMP to make things look more in focus. It would be nice to find something a bit more powerful though.

  • Wow never heard of any of these. I'll have to check them out

  • Learning something new here; never used any of these programs. Now I want to learn how though.

  • These are great! I've used both of these before for open-source graphics editing.

  • I would imagine finding one for free that's quality would be the hard part

  • Have never used this program, but would imagine that a good search of AI would be most helpful.

  • I haven't heard about Pixel phones being able to do this. Do you have a link to more information?

  • I was going to put my two cents in but after reading other comment's I would just be repeating other's, many of these site's should work for you.
